Abstract: ABSTRACT OF THE INVENTION     A digital induction resistivity logging tool is disclosed for digitally measuring both the in-phase (R) and quadrature (X) phase components in a receiver signal generated in response to transmitter induced currents flowing in the earth's subsurface formations.  The digital induction tool includes a digital sinewave generator for generating a highly phase stable, low distortion transmitter signal, the frequency of which is selectable from among a plurality of transmitter frequencies.  One phase sensitive detector is used alternately to detect both the R and the X phase component signals.  Automatic phase compensation is included to periodically compensate for both static and dynamic temperature dependent phase shift errors due to circuits of the tool involved in the component measurements.  A floating point analog-to-digital converter capable of handling the wide dynamic range in the detected phase component signals is provided to convert the phase detector output into digital signals.  Selection of the transmitter frequency may be based on optimizing the measurement of a characteristic of the formations being encountered by the tool.  A linearization correction function is obtained periodically for the tool transfer function as the tool is being used in normal logging operations.  The function is then applied to measurements taken subsequently.

Abstract: ABSTRACT OF THE DISCLOSURE          A hydraulic motor circuit includes a hydraulic breaking feature which reduces the stopping time of the motor when the motor is turned off by stopping the flow of hydraulic oil to the motor.  Conventionally, the control valve used in such circuits places the motor ports in communication with each other via the valve when the latter is placed in its neutral position, thereby permitting the motor to continue operation for a period of time due to inertia of the motor parts and of the driven elements. According to the present invention the control valve when placed in the neutral position blocks oil flow between the valve and the motor, and a pressure relief device is provided for relieving oil from the motor exhaust connection into either the other motor connection or into the reservoir of the hydraulic circuit.

Abstract: ABSTRACT OF THE DISCLOSURE         Plant host acceptable microorganisms, which are ice nucleation deficient and use at least one nutrient from the plant also used by ice nucleating native microorga-nisms, are applied to a plant part at an early stage in the growth cycle.  The multiplication of the native ice nucleating microorganisms is inhibited, so that under nor-mal frost conditions encountered in the field, frost damage is substantially diminished.  The non-nucleating microorga-nisms may be obtained by special selection procedures, selecting from naturally occurring microorganisms or muta-genized microorganisms, where additionally the organisms may be transformed to provide for other desirable properties.         The following organisms have been deposited at the A.T.C.C. on 13 August, 1981:          Pseudomonas putida A510-1 granted accession No. 31947,  and Pseudomonas fluorescens A506 granted accession No. 31948.

Abstract: AN ADAPTIVE IF EQUALIZER FOR DIGITAL TRANSMISSION           Abstract of Disclosure A radio signal will often suffer from amplitude and group delay distortion caused by multipath fading.  An adaptive equalizer, which effectively cancels the amplitude distortion effects, is based upon the use of control voltages derived from selected por-tions of the IF band; said control voltages being selectively ap-plied to bump and slope equalizer sections to cancel the effects of amplitude distortion.  Cancellation of group delay distortion is predicated upon its being proportional to amplitude of the slope correction required.  Thus, group delay correction is introduced in relation to the slope correction introduced to compensate for dis-tortion introduced during normal multipath propagation conditions.

Abstract: TRUE SINGLE ERROR CORRECTION SYSTEM Abstract A scheme for true error correction and multiple bit failure detection for a memory system using multiple data bits per chip.  An H-Matrix results in syndrome generation of bits that are unique for single bit failures that will not match syndromes generated by multiple bit failures.  All multiple bit failures are detected without miscorrecting any single bits that have not failed.  Single pass logic employs all syndromes in parallel inputs to determine the presence of a single bit failure for subsequent correction and also detects the presence of multiple bit failures.

In the absence of an oxidation catalyst, this aqueous system is contacted with gaseous molecular oxygen at an oxygen partial pressure of at least about 50 psi and a temperature of at least about 80°C.  The resulting oxidation converts the tertiary amine to the respective amine oxide in fairly high yields without significant formation of other reaction products.

Abstract: ABSTRACT      The thickness of the layer of remaining molten metal at the bottom of a container is measured on tapping molten metal from the container. An alternating magnetic field is generated with a frequency such that the penetration depth (.delta.) in the metal is of the same order of magnitude as the residue thickness of the melt layer of interest for measure-ment. The alternating magnetic field is generated such that to begin with field components are reflected at a horizontal surface of the melt layer and towards an alternating mag-netic field detection position. When the thickness of the melt layer decreases and approaches the residue thickness, less and less field components will be reflected at the sur-face of the melt and pass instead through the remaining melt layer. The resulting change in detected alternating magnetic field is utilized, e.g. for triggering an alarm or breaking off tapping in some other way.          (Fig 1b)
